Passive elasticity properties of $\mathit{\text{Octopus}}\mathit{\text{rubescens}}$ arm

In this report, passive elasticity properties of $\mathit{\text{Octopus}}\mathit{\text{rubescens}}$ arm tissue are investigated using a multidisciplinary approach encompassing biomechanical experiments, computational modeling, and analyses. Tensile tests are conducted to obtain stress-strain relationships of the arm under axial stretch. Rheological tests are also performed to probe into dynamic shear response of the arm tissue. Based on these tests, comparisons against three different viscoelasticity models are reported.
